Javascript Error Checking

[wrichards8]

It might be an idea to do a tutorial on how to use Javascript to validate a form before sending to the server for processing, like the way Google do with gmail. This is something which I've always wandered how to do, easily done with PHP but there's little point wasting bandwidth just to have the server spit out an error about how a username is too short

The problem with anything JavaScript is that people are generally only interested in the jQuery way to do things and that's not how I do JavaScript

I'll see what I can do anyway
